Cranberry Lake Park: Golden Meadows Host Migrators…and Last Minute Mating!

The golden Eastern Meadow at Cranberry Lake Park in early September

Goldenrod! A variety of different Goldenrods gild Cranberry Lake Park in early autumn. Their bounty of nectar and pollen and the insects they attract make Cranberry Lake an ideal stopover for migrating birds and butterflies as they prepare for their long journeys. So cheer for Goldenrods as they feed wildlife, but don’t blame them for your fall allergies – blame ragweed!

Year ’round birds and summer residents have almost finished molting and are also stocking up energy for winter or the migration. And a surprising number of insects are also preparing by busily mating one last time, leaving behind eggs or chrysalises that can bring forth young next spring and summer. Lots going on within this carpet of gold!

Migrating Birds –  Some Stayed All Summer; Some Just Stop Briefly for Rest & Refueling

Now’s the time to train your binoculars on any shaking leaf you see. It might be a fall migrator! Colorful, tiny warblers and vireos that are just passing through on their way south are well worth a pause to look into the shrubbery, as you’ll see below! But don’t forget to wish “bon voyage” to the migrators who arrived last spring and sojourned with us all summer. Many are finishing up their molts and readying for long journeys to the southern US or even Central and South America. We saw all of the birds shown below on the bird walk last week at Cranberry Lake Park.

Migrators from Farther North:  Just Passing Through

The trees are aquiver with fall migrators, travelers that bred up north and only briefly stop to rest and refuel around our woods and meadows. The most colorful ones that we often hear but can’t see are warblers and vireos. These little birds travel on the night wind because it’s safer. Hawks, eagles, and other birds that might see these small birds as food migrate during the day so that they can ride the thermals!

My camera and I are not quite quick enough to catch a lot of these tiny, fast-moving birds. So to share them with you, I’m relying on photos of other photographers with the skills, equipment and sometimes sheer luck to capture these little beauties!

The Blue-winged Warbler (Vermivora cyanoptera) breeds at Cranberry Lake Park, but the birds we’ve seen in the last week were probably moving through from further north. This fine bird shows off its black eyeline and blue wings with white wingbars in a gorgeous photo taken by gifted local photographer Joan Bonin:

Nashville Warbler (Leiothlypis ruficapilla) was also too quick for me.  But here’s one I did manage to catch as it passed through in the autumn of 2016 on its way to Central America.

Summer Visitors: The Migrators that Come Here to Raise Their Young

Some avian migrators see our parks as a great place to raise their young, so they come in the spring and stay for the summer. Having finished breeding and molting, they are now preparing to leave for points south. The male Common Yellowthroat’s  (Geothlypis trichas) “Witchedy – witchedy” song accompanied me often during the summer months as he and his mate raised their young. But you may here his “chuck” call as he hops among the branches stocking up on insect protein before leaving for Florida.

The Common Yellowthroat stops singing its “witchedy-witchedy” song in the fall and prepares to migrate.

Both the male Common Yellowthroat and his mate did a complete molt in July or August and now have fresh feathers for the trip. She’s bit more secretive than the male as she feeds on beetles, ants, bees (!), dragonflies and  grasshoppers within the golden fields. Usually she’ll leave a week or two later than the male.

The female Common Yellowthroat will be around a bit longer than her mate.

Last spring the Wednesday morning birders heard a Black-throated Green Warbler (Setophaga virens) singing its mating song along the Hickory Lane at Cranberry Lake. And this week, the birders spotted one flitting high in the trees. Perhaps it nested here to raise its young, or it could be just passing through our parks in spring and fall. Here’s  a photo I took of a male during the spring migration this year.

The Black-throated Green Warbler may have nested here this summer or he may be just passing through both in the spring and fall.

High in a snag, a Cedar Waxwing (Bombycilla cedrorum) paused briefly to survey the golden eastern meadow one afternoon. Many waxwings go into lower Canada to breed, but I’ve seen successful nests in our parks, too, so this one may have been a summer resident. Some will move south for the winter, but many waxwings will stick around during the cold months.

his Cedar Waxwing may have spent the summer with us or could be migrating south from Canada.

House Wrens (Troglodytes aedon) become quite secretive after breeding. But this one popped out of the greenery for a minute. It appears to have completed the late summer molt and is prepared to start south between now and mid-October.

The House Wren has raised its young here, molted and will be leaving shortly for Florida and other southern states.

A curious juvenile Field Sparrow (Spizella pusilla) peeked at me from dense shrubbery along the trail, too.  The migration of Field Sparrows is not always predictable. Some migrate, some don’t, and some migrate one year but not the next, according to the Stokes’ Guide to Bird Behavior (Vol.2). If this one does migrate, it may join a large flock with Chipping Sparrows as well as other Field Sparrows.

If this Field Sparrow chooses to migrate this year, it will probably join a larger flock. Or it may just stay put!

On one of my Cranberry walks, I spotted some Wood Ducks  (Aix sponsa) far across a well-hidden wetland. They were males who’d chosen this secluded spot to begin their molt out of the summer “eclipse plumage” into their fancy choosing-a-mate plumage. This one looked a bit rough at the moment, but well on his way to his courting colors. As I explained in last week’s molting blog, males molt earlier in the summer to camouflage themselves as females and then molt again in the fall, a time when they compete for a mate to breed with in the spring.

A male Wood Duck almost finished with the molt from his “eclipse plumage” to his courting feathers.

I often hear, but rarely see,  the vireos at Cranberry Lake. But I did get to see a Warbling Vireo (Vireo gilvus) in the spring. A rare treat, since it loves to sing high in the treetops! Its plumage is modest but its song is impressive!  The birders saw one lingering in our park for a while before departing for points south.

Warbling Vireos are often heard high in the trees, but not as commonly seen.

Occasionally I get a quick look at a Red-eyed Vireo (Vireo olivaceus). But Bob Bonin, Joan’s husband and another gifted photographer, got a much better photo than I have so far! This week it too was hanging out with other migrators.

Butterfly Migrators

Birds, of course, are not the only creatures migrating through our parks this autumn. Monarch Butterflies (Danaus plexippus) fluttered everywhere at Cranberry Lake Park in the last few weeks.  This “super-generation” of  fragile creatures – the ones that will fly 3,000 miles to Mexico – were swooping and diving over the meadows at Cranberry Lake, feeding on the acres of Goldenrod. So glad that we provide these master migrators with such a feast!

The tattered Giant Swallowtail (Papilio cresphontes) below looks lightly worn.  Let’s hope that attests to its having mated here this summer after its migration to Cranberry Lake.  These huge butterflies seem to be expanding their range north. Possibly due to climate change, Michigan now often has frost-free Septembers. So if mating was successful, the caterpillars of this very large butterfly may survive inside their chrysalises and hatch in our parks next spring.

This Giant Swallowtail looks a bit tattered at the end of a summer at Cranberry Lake Park. Due to mating? Maybe.

Last Chance for Progeny!  Insects Still Mating in the Meadows

Among the Goldenrod, insects seek out mates in a last ditch effort to leave offspring for next summer. A pair of Goldenrod Soldier Beetles (Chauliognathus pennsylvanicus) rendezvoused on a Bull Thistle  (Cirsium vulgare) – a potentially risky place to mate since a bird might think they make a tasty contrast against the blossom!

Goldenrod Soldier beetles mating on a Bull Thistle

A pair of tiny Pearl Crescent butterflies (Phyciodes tharos) also decided that a warm September afternoon provided the ideal time for mating.

A pair of Pearl Crescent butterflies mating in eastern meadow at Cranberry Lake Park.

And two Ladybugs chased around a Goldenrod stem, one frenetically holding on to the other. I couldn’t really determine whether they were mating or fighting! Clearly, one was more interested in escape and one was in hot pursuit. They were moving too fast for a great shot or a definite identification. My guess is that they were the invasive Asian Ladybugs (Harmonia axyridis). Unfortunately they are more common these days than our native Nine-spotted Ladybug (Coccinella novemnotata) and come in highly variable colors and patterns.

Two ladybugs chased each other around a Goldenrod stem – mating or aggression?

This tiny Red-legged Grasshopper (Melanoplus femurrubrum) had probably spent the night near the stalk of the Common Milkweed (Asclepias syriaca), wisely hidden from predators among its withering leaves. It will molt multiple times before mating and leaving eggs in the soil to emerge next summer.

A Red-legged grasshopper nymph probably spent the night within this Common Milkweed plant.

The edge of a meadow, near a wetland, might be an ideal spot for a female Great Blue Skimmmer dragonfly (Libellula vibrans). She could be spreading her wings in hope of attracting a mate. If successful, the aquatic plants nearby could host her fertilized eggs. Or while waiting for a likely male, she might just have a great perch for hunting unsuspecting prey!

A female Great Blue Skimmer sunned herself on a cool morning, possibly trying to attract a mate – or just hunting for the next unwary insect!

Spider Art On a Misty Morning

Early fall mornings are an excellent time to appreciate the art of the spiders. Warm days followed by cool nights leave heavy dew on spider webs, and when the sun makes them visible, they are dazzling. How about this lovely creation of an Orb Weaver spider (family Araneidae) drooping with the weight of the dew but subtly reflecting the colors of the sun’s spectrum!

The sun reflecting on the dew in an Orb Weaver’s web.

Another intriguing web, though not as beautiful, is cleverly constructed.  The Funnel Web Spider (Circuria species) lays a sticky sheet of web across the grass, which would be difficult to see were it not for the dew. At the edge of the web, it weaves a tunnel where it lies in wait for unsuspecting prey.  Above the sheet, it weaves an irregular network of silk designed to knock flying insects into its sticky net below. You can see the funnel at the back of this web below.

The Funnel Web Spider’s trap for flying insects with a nifty funnel in which the spider can wait for its prey unseen.

Frogs Underfoot!

As I skirted the edge of wetlands one Sunday, it seemed that a frog sprang out of the grass at every step! Most of them were Northern Leopard Frogs (Rana pipiens), their emerald green backs covered with circular black dots outlined in pale gold. Their dark eyes encircled with gold add to their glamour. Pinkish dorsolateral ridges are another distinguishing field mark. They shine like cloisonné in the deep grass!

Leopard frogs big and small sprung out of the grass near wetlands.

Until last week, I’d never noticed Pickerel Frogs (Rana palustris) at Cranberry Lake. These smaller frogs have somewhat rectangular spots that line up along the frogs’ back in neat rows. They are smaller than Leopard frogs. They tend to be brown (though they are sometimes green too), so I’m fairly sure this is Pickerel frog below.

Pickerel Frogs have more rectangular spots in rows down their backs, rather than the more random round spots of Leopard Frogs. So I think this is Pickerel frog, but I’m not positive!

And Finally, the Native Plants that Make It All Possible!

The plants, though not as often noticed by hikers, provide sustenance for all these creatures as the base of the food web. Butterflies sip their nectar. Bees and wasps feed pollen to their young. Other insects munch on leaves or make winter homes in the stalks. Birds, reptiles, amphibians, and mammals eat all parts of plants, or the insects that live on them. So here’s a gallery of  just a few of the plants that, along with the plentiful goldenrods, have bloomed in sun and shade to sustain the beauty and life of Cranberry Lake Park in late summer.

Autumn Mornings:  Not To Be Missed!

Mist rising in a meadow beyond the trees.

On our September bird walk at Cranberry Lake Park, we arrived on a cool fall morning. The previous day had been unseasonably warm, but a north wind sailed in overnight. The cool air had created heavy dew, leaving silver droplets that set the spider webs shining. The morning sun on the moist leaves created the fine mist you see above, rising  from a meadow beyond the Hickory Lane. What a sight! – the makings of future clouds floating like silver smoke above the wildflowers. A wave of migratory warblers and other small birds had arrived on that night wind. The birders watched, binoculars up, as these travelers hopped busily in the branches, feeding on the plenty of insects attracted by fields full of blooming fall wildflowers. And all of this beauty is gratuitous – unearned, just gifted to us if we just put on our shoes and head out the door! Consider escaping from the busy-ness of life for just an hour this week. Let these beautiful fall days lure you to the parks and savor the gifts that nature so generously offers to all of us.

NestWatch: Being Citizen Scientists in Our Backyards and Parks

A faithful male Rose-breasted Grosbeak takes his turn on the nest at Bear Creek Nature Park.

On March 21, Dr. Ben VanderWeide, the township’s Natural Areas Stewardship Manager, shared a Cornell Lab of Ornithology presentation on how to safely and accurately monitor bird nests as citizen scientists. Cornell Lab and other researchers count on citizen scientists to provide important information on the nesting success of common birds in our backyards and our parks. If you’re intrigued by this introductory information, there’s a lot more available at www.Nestwatch.org. It’s an amazing resource, as you’ll see by all of the links below!

First, the Rules of the Road

The Eastern Kingbird looked proud of her handiwork once she finished her nest.

Cornell’s Nestwatch has an official “Code of Conduct” for nest monitors to ensure that the data is collected while protecting native birds, their nests, eggs, and young. It’s important that monitoring doesn’t attract predators and that parent birds don’t desert the nest.

  • Please don’t touch the nest, the birds or the eggs when checking nests or nest boxes!  Migratory Birds are protected by the Migratory Bird Treaty Act.  They cannot be harassed or harmed.  The only exceptions are those of aggressive invasive bird species like House Sparrows (Passer domesticus) and European Starlings (Sturnus vulgaris) that are not from North America.  (See more info on predators below.)
  • Don’t check nests in the early morning, which is when birds typically lay their eggs.  If the female leaves the nest during monitoring, the eggs may become too cool.  Afternoons are best for monitoring.
  • Avoid nests during the first few days of incubation. Only approach if the parent bird has left the nest.
  • If monitoring a nest box, tap softly on the box to allow the female to leave if she’s present. Or try singing or talking softly as you approach the nest.
  • Don’t approach nests when baby birds are close to fledging so they won’t try to leave the nest before they are ready. Once young birds are alert and fully fledged, only observe from a distance.
  • Avoid monitoring nests in bad weather like cold, rain, etc., when birds need the nest or nest box for protection
  • Don’t check nests at dusk or after dusk when females may be returning. Again, afternoons are best. The exceptions, of course, are owls who leave their nests at night.
  • Approach and leave the nest site from different directions at each visit so that you don’t create a path for predators like cats, raccoons, etc.
  • More details about the “Code of Conduct” at this link

Collecting and Recording What We Learn

A Cedar Waxwing nestling
  • Visits to the nest should be no longer than a minute. Take a quick look and jot notes at a distance. Use binoculars for more distant cup nests.
  • Check the nest every 3 or 4 days. Checking more often risks disturbing the nest; less often makes the information less useful.
  • Record when the first egg was laid. Birds normally lay only one egg per day, so the number of eggs tells you when she laid her first one. Easy, eh?
  • Record the number of eggs and any interesting bird behavior. (Cornell provides data sheets for this.)
  • Record your data at Nestwatch.org. If you’re working on backyard birds, start an account and you’ll be provided with an online form for entering your data. If you want to volunteer to monitor in our parks or along the Paint Creek Trail, please join our Oakland Township Parks NestWatch Chapter by contacting Dr. Ben at bvanderweide@oaklandtownship.org or call the office at 248-651-7810. You’ll need to take a brief quiz after reading the Code of Conduct material at Cornell in order to be a certified bird monitor.
  • More details on collecting data at this link.

Finding Nests in Our Backyards

A male Yellow Warbler holds a bright green caterpillar for his mate at Bear Creek
  • Check out information on typical nest locations and materials for the birds in your yard by going to http://www.allaboutbirds.org. or a bird/nest field guide.
  • Watch where males are singing to establish their territories or listen for females who sometimes sing from the nest.
  • Watch for birds carrying nesting material like moss, twigs or grass.
  • Watch for birds carrying food, like caterpillars or worms, to feed the young.
  • Listen for frantic calls of young birds begging to be fed.
  • Check out areas where you’ve seen nests previous years. Though birds seldom reuse the same nest, they often nest in the same area.
  • More details  on finding nests here.

Setting Up and Monitoring Nest Boxes

Dr. Ben and Tom Korb are trying two different kind of Eastern Bluebird (Sialia sialis) boxes in the township – the traditional ones seen above, and Petersen boxes (see left) which have a more triangular shape.

A Peterson bluebird box

We’ll learn which style our bluebirds prefer. They’ve paired the two types bluebird boxes to see which box design our local bluebirds prefer. Paired nest boxes may also help with competition from Tree Swallows. Others have found that if Tree Swallows (Tachycineta bicolor) occupy one box, they will live peaceably with bluebirds next door. We’ve also installed American Kestrel (Falco sparverius) boxes and a box for smaller birds such as chickadees, nuthatches, or Prothonotary Warblers (Protonotaria citrea).

For details on building/buying nest boxes for your back yard, check out this helpful page on nest boxes at  Nestwatch. For more detailed plans on bluebirds and their houses, check out the website of the North American Bluebird Society or this link at Sialis.org. Nestwatch even shows you the right house for the birds in our geographic area.

Beware of Predators!

Predators can approach native birds from the sky and the ground. (Click on photos to enlarge; hover cursor for captions.)

Ground Predators
  • Raccoons and outdoor or feral cats are major predators for birds. A well-respected, peer-reviewed study cited by Cornell found that as many as 1.3 to 3.3 billion birds are killed by cats each year in North America. They are skilled bird hunters! And raccoons can wipe out a whole group of nests in an evening!
  • Keeping pet cats indoors is a great idea if at all possible.
  • Make sure your nest box is at least 6 feet off the ground so raccoons and cats can’t jump on top of the box. If they do, they “fish” for eggs and chicks through the hole.
  •  The right roof and predator guards on the bird house pole can make a big difference.
  • Avoid leaving pet food or birdseed on the ground, which encourages predators.
  • Keep your nest box away from overhanging trees to keep squirrels from dropping on them and chewing the holes to get in.
  • Snakes can be deterred by locating nest boxes away from brush piles or by putting a metal collar/predator guard below the nest box on the pole.
Bird Predators

Aggressive, invasive birds, especially the House Sparrow and the European Starling, will attack and kill native birds, their eggs and their young to take over a nest box. Because they are non-native and plentiful, they are not protected by the Migratory Bird Treaty Act.  So how to deal with these predatory characters?

  • If you don’t want to deter invasive birds, please  consider not putting up bird boxes. These invasive birds are already abundant and  actively attack and kill our native species. Providing them with food and a nest merely exacerbates the problems for native birds.
  • Choosing an appropriate entrance hole size on a nest box is important. Starlings can enter and attack American Kestrels in their boxes – but starlings are too large for a bluebird box if the entrance hole is the right size. House Sparrows, however,  can easily attack bluebird boxes. NestWatch has more information on passive and active means of deterring these non-native predators – from changing nest location to removing nests and eggs or trapping adult birds.
  • Be sure you know what Starlings look like and are able to distinguish House Sparrows with their black triangular bibs from our many species of native sparrows.
  •  These two invasive birds make messy nests with bits of plastic, cigarette butts, paper, etc. so distinguishing them from native nests is easier once you are informed about the appearance of your native bird’s nest.
  • Native birds, like House Wrens (Troglodytes aedon),  occasionally attack other birds to take over a nest as well. And native Brown-headed Cowbirds (Molothrus ater) lay their eggs in the nests of other birds. Because these birds are naturally occurring species in our area, they are protected by the Migratory Bird Act and should not be removed or harmed.
  • Bees, wasps, squirrels and mice can inhabit nest boxes at various times of the year. Nestwatch has info on coping with them, too.

So Why Become  a Nest Monitor?

This slideshow requires JavaScript.

Helping our native birds raise their young in safety is crucial to slow the declining numbers of many bird species. Bluebirds, for example, were threatened until citizens began a campaign of installing and monitoring bird boxes for these azure beauties. The data from nest monitors since NestWatch began in 1965 has provided vital information on over 600 species and resulted in 133 scientific articles and 9 ongoing studies. With the data the public collects, researchers can detect  shifts in bird populations related to landscape and climate change. Saving native birds is important to preserving the beauty of our local natural history.

But beyond all that, c’mon!  What’s more delightful than baby birds? Being a friend to native birds is always good for us, as well as for our feathered friends.

Photos of the Week: Nature During “The Big Freeze”

The mighty oak at Ilsley Park on a wintry morning

Since we seem to be heading into a warming trend, I thought I’d share the odds ‘n’ ends of what I’m calling The Big Freeze, those recent days of frigid temperatures and wind.  In the interests of preserving my camera and my numb fingers, my hikes during  the Big Freeze were shorter and the photos were fewer.

Blog by Cam Mannino

But as usual, I delighted in the sightings or even the  signs and traces of other creatures, including other humans, who shared the bitter temperatures with me.  On those frigid, silent days, I found myself appreciating the slightest visual treat that passed unnoticed in the lushness of summer  – a rock, a mud puddle, snow-covered mushrooms.  So here’s a sampling from Bear Creek and Charles Ilsley Parks of what can make a walk worthwhile even on the zero degree days of a challenging winter.

Wildlife Braving The Big Freeze

Flocks of Cedar Waxwings brightened a cold morning at Bear Creek Nature Park with color and friendly chatter.

Birds are rarer sights for me on super cold winter walks, so what a treat to come across a flock of Cedar Waxwings (Bombycilla cedrorum) on two different walks at Bear Creek Nature Park. The high-pitched whistling as these winter social groups swooped and settled was quite cheering during The Big Freeze. Here are some other creatures that shared those bitter morning walks with me.

Far in the distance early one morning, a Red-tailed Hawk plumped its feathers for warmth as it surveyed Bear Creek Nature Park.
American Red Squirrels (Tamiasciurus hudsonicus) don an auburn stripe down their back and tail for extra warmth on winter days.
A Northern Cardinal (Cardinalis cardinalis) dove through the bushes  foraging for food one snowy morning.
The Red-bellied Woodpecker’s “kwirr” call announces its presence. Its drumming is rapid, short and surprisingly soft for such a large bird.

Though I heard more creatures deep in the brambles and watched birds fly overhead, I only caught a few with my camera.  Some animals only left their tracks behind. On a bird walk at Charles Ilsley Park, we saw the neat tracks of two coyotes who’d trotted along in the moonlight the night before. Coyotes make straight, single tracks, placing their back feet in the tracks of their front feet to save energy. One of the birders said he’d heard that the coyote’s tail can leave a slight drag line as seen in the closeup below. I couldn’t find a source for that, but it makes sense since coyotes run with their tails down, rather than up like wolves or dogs. Click on the photos to enlarge; hover your cursor for captions.

A Meadow Vole (Microtus pennsylvanicus), aka a Meadow Mouse,  must have crossed the path at Bear Creek Nature Park on a snowy night and then disappeared by burrowing into the snow. Lucky for this little creature that the coyote wasn’t around! (Meadow Vole photo by Wolfgang Siebeneich at inaturalist.org.)

I’ve never seen a Pileated Woodpecker (Dryocopus pileatus) at Bear Creek Nature Park, though others have. But I did see the hole one had recently excavated in a tree  in the Oak- Hickory forest there – with this “carpenter’s” wood chips scattered below. (Woodpecker photo kindly lent by Joan Bonin, a gifted local photographer.)

Evidence of Humans at Play During the Big Freeze

It’s always cheering to come upon evidence of other people using our parks to just play in the snow.

Odds ‘n’ Ends that Caught My Winter Eye

The austerity of winter reveals landscape features unnoticed in the lushness of spring and summer.  The birding group marveled at a fast-running spring  flowing out into the snow at Charles Ilsley Park which had been dry or hidden in the dense growth of the field the rest of the year.

At sunset one afternoon, I rounded the corner of the shed at Bear Creek Nature Park and saw a pink and blue sunset glowing in a puddle of melted snow.

The graceful “bones” of last year’s wildflowers, clusters of half-moon shelf mushrooms, even an unusual rock catch my eye when framed in white. (Use pause button if you need more time for captions.)

 Beauty in the Big Freeze: Appreciating the Small Things

Plant material below the surface colors the ice on a wetland at Bear Creek Nature Park.

Sometimes it’s just the pale green and lavender of ice in a wetland or the high whistle of a swoop of Cedar Waxwings. The scarlet flash of a Cardinal or a dancing snowman can lift your heart on gray winter day. Feathery snow settling on a seed pod or the gaudy beauty of an early sunset – it’s just a matter of taking in beauty in smaller, more subtle doses that can buoy our spirits in the dark cold of a Michigan winter.

Watershed Ridge Park: Restoration Off to a Colorful Start!

 

Wildflowers re-establish themselves in a meadow at Watershed Ridge after invasive shrubs are removed

Watershed Ridge, at the corner of Lake George and Buell Roads, is not yet an accessible park. Trails have yet to be created for exploring its forests, wetlands and meadows, though they are planned for the future. Large areas of the land are still under cultivation for agriculture; local farmer, John Fogler, rents fields within the park to plant soy beans and pumpkins. (Click on photos to enlarge; hover cursor for captions.)

But last fall, our Natural Areas Stewardship Manager, Ben VanderWeide, began removing an almost impenetrable cover of invasive bushes that had taken over part of this beautiful piece of land. And suddenly, the graceful contours of the land came into view.

The slopes of Watershed Ridge after last fall’s removal of invasive shrubs

The rolling slopes looked lifeless then. But what a transformation this spring and summer as sun finally reached the native wildflowers!

The sloping landscape of Watershed Ridge Park this summer after the removal of invasive shrubs

Part of the reason Ben chose this area for restoration was that he’d noticed unusual native plants struggling to survive in the shade of invasive bushes like autumn olive, glossy buckthorn, privet, and such. Last autumn, Smooth Aster (Symphyotrichum laeveand a small orchid called Ladies’ Tresses (Spiranthes species) thrust their stems into the cool air. (Here’s a photo of the little orchid as it looked at the Wet Prairie on the Paint Creek Trail.)

Ladies Tresses, a small orchid, is a fall wildflower that Ben saw at Watershed Ridge last autumn.

Right now I’d advise anyone to be cautious about  walking through Watershed Ridge since it’s easy to get disoriented on 170 acres without trails (though a compass in your phone helps, I find!). Hikers need to use the edges of the farm fields so that they don’t damage the crops. The woody debris on the ground makes walking a bit tricky  and there’s a fair amount of Poison-ivy (Toxicodendron radicans) to avoid. Photos below might help those afraid of all 3-three-leaved plants. The one on the left is poison ivy.  Note the “thumb” on the leaves which is missing from other three-leaved plants like the Black Raspberry (Rubus occidentalis) on the right. Poison-ivy often has reddish “feet” when it’s climbing a tree and grows along the trunk rather than around it.

So for now, perhaps consider an easier alternative.

Birds Grace the Simple Entrance off Buell Road

The best spot to park is on Buell Road at the firewood pickup site (1650 W. Buell Road is the approximate address – click here for a map). Just to the west you’ll see a work area for Parks and Recreation staff that includes a pole barn and bulk materials storage. This work area is closed to the public, but you’re welcome to explore the rest of the park.

The old fence rows near the entrance on Buell Road have many trees, shrubs and vines, so birds nested happily around the area this summer. In mid-July, this area was full of fledglings trying out their wings and pestering their parents. A flock of young Eastern Bluebirds (Sialia sialis) settled on limbs and fence posts, begging to be fed while their beleaguered adults either surrendered or tried to escape their noisy youngsters. (Click on photos to enlarge; hover cursor for captions.)

A young Eastern Phoebe (Sayornis phoebe), however, was off on its own, trying out its wings, exploring the pole barn (sheds are popular Phoebe nest sites) and flying down into the grass like any adult Phoebe might.

A young Phoebe exploring the shed at Watershed Ridge – a very typical behavior for a bird that often builds nests in human structures.
The same Phoebe in a nearby tree to provide a glimpse of how small this little flycatcher is!

A young Downy Woodpecker (Picoides pubescens) was also off on its own and looking a bit dubious about what to do next as it sat in a nearby pine. This may be a young male since it appears that its juvenile red cap is slowly receding into the red spot that a male sports on the back of its head.

A juvenile Downy Woodpecker considers what to do next.

I failed to get decent photos, but two weeks ago, a pair of Cedar Waxwings (Bombycilla cedrorum) were still feeding their nestlings, flying back and forth between a tree on the west side of the area to a large willow on the east where they probably were foraging for insects before returning to the nest. Here are two not-so-hot photos!

From mid-July to mid-August, American Goldfinches (Spinus tristis) raise their young. Unlike most native birds, they wait until mid-summer to breed, because they like to line their nests with thistle down, eat the seeds themselves and feed them to their young. Several were flitting among the thistles along Buell Road.

A “High Quality” Woodland Sprinkled with Wildflowers that Love Moisture, Shade and Rich Humus.

When you step into the cool darkness of the woods on a warm summer afternoon, you notice that most of the plants bear modest little flowers compared to sunnier areas. Perhaps that’s because they’ve  evolved growth and reproductive strategies that are different from the large, colorful blooms of a sunny meadow or prairie.

One good example is the unusual flower of a parasitic plant (not a mushroom!) that Ben helped me find, called Indian Pipe (Monotropa uniflora). This small, white wildflower typically grows in forests and lives on the photosynthesis of trees – especially oaks in our area – by tapping into the  mycorrhizal fungi that connect the trees below the soil. As a result, it doesn’t use photosynthesis and contains no chlorophyll. According to the Illinois Wildflower website (a descriptive floral site), “This unusual wildflower is normally found in high quality woodlands” where there is “abundant humus.”  Hooray for Watershed Ridge, eh?

The modest blooms of summer woodland plants primarily attract small bees, like sweat or carpenter bees,  or flies,  rather than honeybees or bumblebees.  They also frequently spread by rhizomes (underground stems) and/or by making bur-like fruits that will stick to any passing animal, including you!

Wildflowers that enjoy dappled light find a home where the woods meets the now-open meadow.

Naturally, mushrooms also thrive in shady, moist places. Near the edge of the woods, I saw what I think are two kinds of highly toxic mushrooms from the genus Amanita. I believe they are either Amanita phalloides or Amanita bisporigera. In any case, Amanita mushrooms are also called “death caps” for good reason –  so admire their exotic strangeness, but leave them right where they are. The yellow one may have been nibbled by squirrels or rabbits who can eat the toxins with no problem.

Wetlands Glow Blue/Green in the Deep Shade of the Woods

One of the wetland pools within the woods at Watershed Ridge

Two wetland pools shine in the darkness on either side of a ridge within the woods at Watershed.  Near the western one, an old log is festooned with a huge number of tiny, stalked mushrooms which I can’t identify. They make quite a show against the dark, wet decaying log on which they are thriving.  (Anyone have an ID for me?)

Ben saw two snappers on a log in one of these woodland pools, but they dove in before I saw them. I did see some of my favorite frogs, though. A small female Green Frog (Rana clamitans) (left) basked on a fallen log, while a male nearby (right) did the same. In the female, the tympanum (circle behind the eye used for hearing) is about the size of her eye; the male’s tympanum is about twice the size of his eye and he has a yellow throat.

At the eastern pool, a tiny, black-masked Wood Frog (Rana sylvatica), perhaps 1/2 inch long, paused for its photo on a leaf. This one’s back and legs are bright green, perhaps from the Water Meal (Wolffia columbiana) or the algae in the pool nearby. It seemed an odd time of year  to find an early spring frog, but Wikipedia says that  occasionally Wood Frogs do breed more than once per year. Maybe the heavy rains contributed to more water and hence more breeding behavior? Just a guess.

At the edge of the soybean field just beyond the wood, every step scared up hundreds of small Northern Leopard Frogs (Rana pipiens). They sprang out of moist grass and huddled beneath the bean plants. These young frogs  take about 70-110 days to develop after the females lay their eggs in the water between May to June. At about 2 inches long, they’re half the size of a mature Leopard Frog. Their numbers have generally been in decline since the 1970’s so what a delight to see so many of them here in the township on a protected piece of land!

A Riot of Color as Wildflowers and Butterflies Reclaim a Wild Meadow

Black-eyed Susans and Butterfly Milkweed “take the field” after invasive shrubs are removed from Watershed Ridge

Step out of the woods and the colorful signs of restoration engulf you. Once shaded-out by invasive shrubs, native wildflowers like Black-eyed Susans (Rudbeckia fulgida) and Butterfly Milkweed (Asclepias tuberosa) in the photo above sprang back into the sunlight that finally reached them.  So exciting to see these plants come back with such vigor in the first season after the invasives are removed! (Use pause button to read captions.)

And with the wildflowers, of course, come the butterflies – but first, one glorious moth! When I first spotted this unusual creature, I thought it must be some sort of bumblebee. But no, it’s the Snowberry Clearwing Moth (Hemaris diffinis). It has fewer central scales on its wings than other butterflies or moths so the wings appear clear in places. It’s odd shape and hovering flight have also inspired the names “the hummingbird moth” (not to be confused with the European one of the same name, Wikipedia tells me!) or the “flying lobster!”  A new creature for me!

This is not a bumblebee. It’s a Snowberry Clearwing Moth mimicking one!

On my first summer visit with Ben, we saw a glorious Eastern Tiger Swallowtail (Papilio glaucus) sipping from some of the bee balm which emerged in great waves of color across the restored meadow this summer. What a sight!

A female Eastern Tiger Swallowtail sips nectar from the great swath of bee balm that now flows across the restored meadow.

Having seen the Spicebush Swallowtail butterfly (Papilio troilus) for the first time at Charles Ilsley Park a few weeks ago, I saw another male at Watershed Ridge.  The clue is the wash of blue scaling on the wings. A week later I saw another one near the shed which was either the female, which has a less intense wash of blue scaling, or a tattered male who had already lost some of his scales. That Spicebush continually tried to chase off a female Monarch (Danaus plexippus) who was patrolling the same patch of flowers last weekend. The scales on her wings looked quite worn as well. Perhaps they’d worn each other out with all that chasing! I saw some fritillaries dancing together at a distance but not close enough for a shot. But the little Orange Sulphur  (Colias eurytheme) was kind enough to pose for a few moments.

The meadow slopes down to a sunny wetland that is probably fed by the creek running through the trees just east of the meadow. The stream bottom is bright orange, most likely a result of iron deposits in the soil. I loved how the sky was caught in the water’s surface as I looked upstream.

The resulting wetland at the meadow’s edge featured flowers that love “wet feet,” like Joe Pye Weed (Eutrochium maculatum) and Boneset (Eupatorium perfoliatum).

With a wetland nearby, dragonflies, flying predators, swooped across the meadow on the hunt for other insects.

A Meadow Under Restoration Gets Us Dreaming

Witnessing the dramatic renewal that takes place when invasive shrubs are removed from park land is simply inspirational. What else, who else might return to this lovely piece of land once the Parks and Recreation Commission has time and the funds to develop this 170 acres? What seeds are waiting in the seed bank for their turn in the sun – perhaps even this autumn when the asters in their varied lavender-to-purple blooms or other autumn wildflowers rise from the earth? What other exotic creatures like the Snowberry Clearwing Moth might be sipping at future flowers? What birds might return to nest here? The possibilities are endless as the Ben and the Parks Commission work to renew the diversity of life which is our township’s natural heritage. So much to look forward to as this park progresses over the next several years!

Back to Bear Creek: Surprise! Unusual Sightings of Birds, Bugs and More

Blog Post & Photos by Cam Mannino

The last two weeks at Bear Creek gifted me with some exciting moments – seeing previously unseen birds, witnessing unusual nesting behavior, watching a turtle struggling to bury her eggs and being surprised by a little butterfly I hadn’t seen for years. So though the blog just visited Bear Creek two weeks ago, I wanted to share the bounty I’m enjoying before the season changes much.

Unusual Birds and the Usual Ones Doing Interesting Things!

As many of you know, I’ve been walking in Bear Creek for 25 years and I’ve watched for owls all that time. They spend their days sleeping right next to tree trunks on high limbs, and despite craning my neck for years, I’d never spotted one. But on the first June bird walk, a fellow birder, Bob Bonin,  spotted one high up in a tree near Bear Creek Marsh. Huge, silhouetted against the morning sky, this Great Horned Owl (Bubo virginianus) wasn’t easy to see, much less photograph. But luckily, I got a few shots before he gave the group an annoyed look, lifted his huge body with his massive wings and flew away. Such a thrill! (Click on arrows for slideshow; use pause button for a closer look.)

A bit earlier that morning, we saw an unusual bird at the other end of the size spectrum. A male Ruby-throated Hummingbird (Archilochus colubris) perched high on a snag behind the Center Pond and turned his iridescent green back to the morning sun. We saw a quick orange flash at his throat but I missed it. The Stokes Guide to Bird Behavior (Vol. I) indicates that males’ throats look brown or black if the light doesn’t hit their necks just right. When I returned on a late afternoon, there he was on the same snag – but this time the afternoon sun caught the edge of his throat which shone gold rather than ruby red. He’s not the most glamorous hummer, but I’m glad I got to see a bit of his gleam.

This male hummingbird’s bright throat only shone for a second in the morning sun, so I settled for the light in his eye and his iridescent green back.
The same male hummer’s throat shone gold in the late afternoon sun.

Near the Center Pond, the birders also discovered the nest of a Rose-breasted Grosbeak (Pheucticus ludovicianus) – with the male sitting calmly, tending the eggs or nestlings. Occasionally, he even sang his lovely tune as he waited patiently. I’d read in the Stokes Guides that male Grosbeaks sometime take on this responsibility, but I’d never seen it. On three separate visits, the male was the only one on this nest – though the female may have relieved him at other times. So, Happy Father’s Day to this dedicated Grosbeak dad!

In a willow to the right of the deck in the Center Pond is a beautiful nest.  It’s cleverly attached between two vertical branches about 20 feet up, ingeniously woven and quite large – maybe 9 inches long. During my first 3 visits, only the female’s black tail cocked behind her was visible from the observation deck. Finally one afternoon, I waded into the grass at the pond’s edge and  caught sight of her hindquarters as she fed her young. And then, I saw a fledgling’s head just above the edge of the nest. Ah, this nest was constructed by a female Red-winged Blackbird (Agelaius phoeniceus) – a somewhat eccentric one since Red-wings normally build close to the water and weave their nests among cat-tails or reeds. She’s quite an architect! The location of this elaborate nest makes it nearly invisible and unreachable by predators. Clever mama Red-wing!

Two nests appeared high in a tree on the Walnut Lane. The barely visible, masked eye of the female Cedar Waxwing (Bombycilla cedrorum) peeked through the leaves that camouflaged the first nest spotted by the birders. Since she sat there quietly every time I visited, I’ve included a photo of a Waxwing from a previous year so you’ll  remember how elegant this conscientious mother bird truly is!

Only the masked eye of the female Cedar Waxwing shows above the edge of her cleverly hidden nest along the Walnut Lane.

Across the Walnut Lane, the birders also discovered the nest of a female Eastern Kingbird (Tyrannus tyrannus) who spent several days building her gauzy, somewhat more loosely constructed nest. She proudly stood above it a few days later as it neared completion. The female Kingbird constructs the nest and keeps the male off it until the eggs hatch. Then both parents feed the nestlings. But even during the egg phase, the male stays on a branch nearby to defend the territory for his mate and young.

Another good provider, a tiny male Yellow Warbler (Setophaga petechia) brought a bright green caterpillar to feed his nestlings or mate. In between feeding trips, he’d let loose with his proud song, “Sweet, sweet, I’m a little sweet.” Impressive dad who can bring home the bugs, singing all the while! Bet the female warbler was as impressed as I was.

An Orchard Oriole male (Icterus spurius) serenaded us from a small tree in the middle of a meadow. His long, melodious song sounded much like the third song recorded at this link.  A few Orchard Orioles seem to come to Bear Creek each year – but they migrate south by mid-July. So keep an eye out and an ear cocked soon in the meadows to the east of the Walnut Lane!

An invisible bird, high up in the tree tops, repeated its melodious warble continuously one warm morning. I’ve never seen a Warbling Vireo (Vireo gilvus); they rarely come down from the heights. But fortunately, a great photographer from the iNaturalist website, Steven Mlodinow, has seen one and generously allows others to borrow his photo. Listen for this warbler’s rich melody all summer long, but don’t be surprised if you never spot this elusive summer resident.

Little Surprises Near the Wetlands

At the northeast corner of the Center Pond, a young Painted Turtle (Chrysemys picta) hurried to cover her eggs one hot afternoon. She’s found a likely spot where Ben had cleared away invasive shrubs a couple of years ago. As you’ll see in the video below, she work really hard with her back legs to get the dirt to move. She’d no doubt have preferred sandier soil! But she was determined to see the job done!

I’ve seen Northern Leopard Frogs (Lithobates pipiens) periodically at Cranberry Lake but never one at Bear Creek. But hearing their snoring call near a wetland, I waded into tall grass and found this one, hiding among the greenery. Glad to know this beautiful frog is at Bear Creek, too.

Ben noticed an  Eastern American Toad (Anaxyrus americanus) toad on the path one afternoon when we went to look at nests.  Normally, I only see brown toads, but Wikipedia informs me that “The color and pattern is somewhat variable, especially for the females. Skin color can change depending on habitat colors, humidity, stress, and temperature…Some toads of this subspecies have a more pervasive red and deep brown color, many with red warts on their bodies.”  So this little toad is probably female and the red description  fits  her pretty well.  I wonder if the unusually hot temperatures had an effect on her appearance?  Hard to tell.

Amazing Insects: A Butterfly I’ve Missed for Years, Favorite Dragonflies and the Skills of Tiny Pollinators

Next year, I’ll be looking for the boldly patterned Baltimore Checkerspot butterflies (Euphydryas phaeton) on June 11 or 12. I’ve only seen them on those two dates, 6 years apart! This year, four of them fluttered at a spot in the trail where water runs under the path – a place I’ve often seen other small butterflies feeding on minerals left by the water. Later in the summer, watch for the communal caterpillar webs of these small butterflies (about 2.5 inches) on the host wildflower Turtlehead (Chelone glabra) where these butterflies lay their eggs during the summer and where the caterpillars first feed.

Interestingly, in the fall, Baltimore Checkerspot caterpillars wrap themselves in leaf litter, overwinter and finish developing in the spring. This seems to be a big year for them – so keep an eye out if you see a small, dark butterfly at your feet.

The Baltimore Checkerspot overwinters as a caterpillar.

Different species of dragonflies seem to appear each week to dance among the budding wildflowers and over the pond. The dramatic, yet quite common Twelve-spotted Skimmer (Libellula pulchella) did indeed skim over the tops of grasses in the Eastern Meadow this week. Dragonflies often land, fly, and then come back to the same dry stalk – so if you miss one in your binoculars the first time, wait a moment and you’ll probably see it in the same place again!

A bright green Eastern Pondhawk (Erythemis simplicicollis) dragonfly clung to a grass stem on the western slope. If it’s a male, it will gradually turn blue over the summer. If a female, it will remain green. Probably this one is newly emerged since it’s hunting in a meadow. When it’s ready to mate, it will rendezvous with others  at the Center Pond.

This Eastern Pondhawk is still in the meadow but will go to the pond when it’s time to mate.

A small Dot-tailed Whiteface (Leucorrhinia intacta) dragonfly posed for a face-on selfie at the Playground Pond before continuing its quest to consume as many mosquitoes, flies and other small insects as possible before the day is out. Love its cartoon-like face and the one yellow dot on its tail that give it its name.

Easy to see why this is called a Dot-tailed Whiteface dragonfly, eh?

 

 

 

 

 

 

 

 

 

 

Pollinators are busy all over the park, feeding and carrying the pollen that will bring us next year’s blooms. This may look like a European Honey Bee (Apis mellifera) but Honey Bees are fuzzy all over and this one just isn’t. So it’s more likely to be a Dronefly (Eristalis tenax), a type of Hoverfly (family Syrphidae), which uses its pattern, slight fuzziness and loud hum to mimic male Honey Bees as a way of protecting against predators. Droneflies cannot sting, but a passing dragonfly probably doesn’t take a chance!

This dronefly (a kind of hoverfly) mimicks a bee’s appearance and hum for protection.

I noticed what looked at first like a tiny wasp on this umbel of a native Nannyberry bush (Viburnum lentago) near the Center Pond. But after a bit of research in Pollinators of Native Plants by Heather Holm, I’m going to guess it’s a female Leaf-cutter Bee (family Megachilidae). It has a wasp-y pattern and shape and it’s collecting pollen on its abdomen and on the top of its back leg (look at those jodhpurs!). Leaf-cutters cut small, neat circles out of leaves, hence the name. They then roll up a single fertilized egg and a chunk of pollen in each circle, forming a solitary, cigar-shaped nest which is placed in a hole in the soil, wood or other structures. Such an unusual nest!

Bring a Friend – or Friends! – to Visit Your Favorite Park

Oakland Township Natural Areas manager Ben VanderWeide leads a group of birders at Cranberry Lake Park

I’ve always loved walking alone in the township parks. I can listen to birdsong, stop to look at something tiny like the Little Wood Satyr butterfly below, or enjoy the fresh scents of wood, greenery, the earth after a rain in silence. Solitary walks are contemplative.

But this particular blog testifies to the special pleasures of hiking with interested friends and family. First of all, they just bring more eyes! I’m always seeing things with the birders or with my husband, that I’d never have noticed with just my two eyes (in this case, the owl, the hummer, the oriole, the male grosbeak in his nest and more). But also their curiosity piques mine. They bring specialized interests and knowledge. They often patiently help me find the bird hiding in a leafy tree (“The center trunk at about 2 o’clock…). It’s a different kind of delight to walk with nature-noticing friends. So if all of this nature stuff intrigues you, take some nature-lovers with you on your next walk. Or consider joining our friendly birding group on Wednesday mornings year ’round. We’d love to have you join us! (The schedule is under “Events” at the top of the home page.)
